摘　　要：提高无线通信系统的数据传输速率是第五代移动通信技术(5G)发展的核心动力,毫米波因具有丰富的频谱资源而受到广泛关注。由于工作波长较短,毫米波在传播过程中更容易受环境影响,因此搭建毫米波信道测量系统并建立相应的三维空间信道模型,有利于推动高频通信技术在5G中的应用。根据毫米波的应用场景和技术需求,重点介绍了频域和时域信道测量系统的基本原理和组成方案以及大尺度、小尺度信道模型和对应参数提取方法。最后讨论了6 GHz以上频谱划分和信道模型建立方面的标准化工作进程。To improving data transmission rate in wireless communication system is the core impulse for the fifth generation（5G） mobile communication technology.Millimeter wave（mm Wave） draws much attention because of its abundant spectrum resources.Since the wave length is short,mm Wave is easily affected by the environment.Therefore,to build mm Wave channel measurement system and the corresponding three-dimensional spatial channel model is beneficial for the promotion of the application of the high-frequency communication technology in 5G.According to the application scenario and technical requirement of mm Wave,the principles and composition schemes of both frequency-domain and time-domain measurement systems,as well as the large-scale and small-scale channel models and their parameter extraction methods were elaborated.Finally,the standardization process of spectrum division and channel modeling above 6 GHz was discussed.
